Definitions

  • This invention relates to a starter for the internal combustion engine of, for example, a two-wheeled motor vehicle, as described in the preamble of the claim 1.
  • a starter as described in the preamble of the claim 1 in principle is known from DE-C-457 797. This type of starter may make a capacity of a battery small. The manual operation must be performed all the time of starting up.
  • FIGURE 1 A starterfor the internal combustion engine of a two-wheeled motor vehicle is shown in FIGURE 1 to illustrate a conventionally known internal combustion engine starter of the type to which this invention pertains.
  • the engine has a crankshaft 1 to which a sprocket 2 is secured.
  • An intermediate shaft 3 lies in parallel to the crankshaft 1 and is rotatably supported by a bearing 4 on a stationary member not shown.
  • a sprocket 5 is connected to the intermediate shaft 3 by a rotational variation buffering mechanism not shown.
  • the sprocket 5 is connected to the sprocket 2 by a chain 6.
  • An overrunning clutch 7 has an outer member 7a to which the sprocket 5 is secured, and an inner member 7b fitted about the intermediate shaft 3.
  • a sleeve 8 is disposed between the shaft 3 and the inner member 7b which are rotatable relative to each other.
  • a spur gear 7c is formed on the inner member 7b.
  • a spur gear 9 is secured to the intermediate shaft 3.
  • a large gear 10 meshes with the spur gear 9 and is connected to a speed change gear not shown by a clutch not shown.
  • An intermediate gear 11 is secured to a rotary shaft 12 and meshes with the spur gear 7c.
  • a lever shaft 17 has at one end a clutch portion 17a which engages it unidirectionally with the rotary shaft 12.
  • a kick lever 18 is connected to the other end of the lever shaft 17.
  • the sprockets 2 and 5, chain 6, overrunning clutch 7, intermediate gear 11, rotary shaft 12, pinion 16, self-starting motor 13, self-starting switch 14 and battey 15 form a first cranking mechanism.
  • the sprockets 2 and 5, chain 6, overrunning clutch 7, intermediate gear 11, rotary shaft 12, lever shaft 17 and kick lever 18 form a second cranking mechanism which is manually operable.
  • the manual cranking mechanism makes it possible to start the engine mechanically as will hereinafter be described.
  • the kick lever 18 is actuated to rotate the lever shaft 17 and its rotation is transmitted to the crankshaft 1 through the rotary shaft 12, intermediate gear 11, overrunning clutch 7, sprocket 5, chain 6 and sprocket 2, whereby the engine is started.
  • the rotation of the engine is transmitted to the speed change gear through the sprocket 2, chain 6, sprocket 5, rotational variation buffering mechanism, intermediate shaft 3, spur gear 9, large gear 10 and the clutch not shown.
  • the overrunning clutch 7 prevents the reverse motion of the kick lever 18, etc.
  • the cranking mechanism including the self-starting motor 13 enables the electrical starting of the engine as will hereinafter be described.
  • the self-starting switch 14 is closed to supply electric current from the battery 15 to the self-starting motor 13 and thereby cause it to rotate.
  • the rotation of the output shaft 13a is transmitted to the crankshaft 1 through the pinion 16, intermediate gear 11, overrunning clutch 7, sprocket 5, chain 6 and sprocket 2, whereby the engine is started.
  • the unidirectional engagement of the clutch portion 17a prevents the reverse rotation of the kick lever 18 and the lever shaft 17.
  • the rotation of the engine is transmitted to the speed change gear as hereinabove described.
  • the kick lever 18 and the lever shaft 17 have, however, their own structural limitations which disable them to rotate beyond a certain angle to cause the crankshaft 1 to rotate continuously.
  • An internal combustion engine having a large displacement capacity is particularly difficult to start by the cranking mechanism including the kick lever 18.
  • the cranking mechanism including the kick lever 16 and the cranking mechanism including the self-starting motor 13 are, therefore, both provided for some internal combustion engines of large displacement capacity for two-wheeled motor vehicles, as shown in FIGURE 1.
  • a high torque is required for causing the crankshaft 1 to rotate, especially when starting its rotation.
  • the battery 15 in a two-wheeled motor vehicle has a relatively small capacity due to a limited space available for its installation. It is rapidly consumed, since it is frequently used to start the engine. A reduction in the voltage supplied from the battery makes it more difficult to start the engine quickly.
  • the DE-C-955 642 discloses a combined type starter in which a starter motor is driven after the 75% pass completion of the manual starter device.
  • the crankshaft is mechanically rotated by the second cranking mechanism during the beginning of its rotation which requires a high torque, and is subsequently placed in continuous rotation by the first cranking mechanism including the self-starting motor. It has only a reasonable amount of battery consumption and can be used to start the engine easily even after a reduction in the voltage supplied from the battery.
  • a rising current which is generated in the engine starting mode solely by the cell motor may be prevented by the rotation of the kick lever.
  • the rising current needs a high torque. Therefore there is no problem even if the current is supplied to the cell motor for a predetermined time period after the engine start. It is therefore, an apparatus of greatly improved starting performance and reliability.
  • FIGURES 2 to 4 An apparatus embodying this invention is shown in FIGURES 2 to 4. Like numerals are used to indicate like parts throughout FIGURE 1 and FIGURES 2 to 4.
  • a disk-shaped cam 19 is secured to the lever shaft 17 and a microswitch 20 having a lever 20a contacting the outer periphery of the cam 19 is connected in parallel to the self-starting switch 14.
  • the cam 19 and the microswitch 20 define a means for driving the self-starting motor.
  • the apparatus of this invention is identical to the conventional apparatus in all the other aspects of construction and no further description thereof will, therefore, be made.
  • the kick lever 18 is actuated to cause the cranking mechanism including the kick lever 18 to rotate the crankshaft 1 mechanically as hereinbefore described in connection with the conventional apparatus.
  • the cam 19 is rotated in the direction of an arrow to its position shown by a broken line in FIGURE 3 to close the microswitch 20.
  • An electric current is, therefore, supplied to the self-starting motor 13 to actuate the cranking mechanism including the motor 13 so that the crankshaft 1 which has been urged to rotate by the actuation of the kick lever 18 is placed in continuous rotation, whereby the engine is started.
  • the self-starting motor 13 is operated during the rotation of the crankshaft 1 by the kick lever 18, a relatively low torque is sufficient to place the crankshaft 1 in continuous rotation and does not cause any large consumption of the battery 15.
  • the kick lever 18 is released from pressure, and a return spring not shown brings it back to its original position and thereby returns the cam 19 to its position shown by a solid line in FIGURE 3, whereby the microswitch 20 is opened to discontnue the operation of the self-starting motor 13. It is also possible to actuate only the cranking mechanism including the self-starting motor 13 by closing the self-starting switch 14.
  • the self-starting motor driving means hereinabove described comprises the cam 19 and the microswitch 20, it is equally possible to employ a means of different construction comprising a microswitch for detecting the rotation of the kick lever 18 and a timer responsible to its output for supplying an electric current to the self-starting motor 13 for a predetermined length of time.
  • first and second cracking mechanisms have been described as sharing certain mechanical connecting parts from the sprockets 2 and 5 to the rotary shaft 12 for the intermediate gear 11, it is, of course, possible to construct those two mechanisms completely independently of each other.
  • This invention is applicable not only to a starter for the internal combustion engine of a two-wheeled motor vehicle or an outboard, but also to a starter for an internal combustion engine of any other type.
